Transient Global Amnesia Linked to Impairment of Brain Venous Drainage: An Ultrasound Investigation.

Front Neurol 2019 5;10:67. Epub 2019 Feb 5.

Department of Neurology, First Hospital of Jilin University, Changchun, China.

Previous neuroimaging and ultrasound studies suggested that compression and stenosis of the internal jugular vein (IJV) in patients with transient global amnesia (TGA) may impair IJV drainage, while a patent IJV releases intracranial pressure caused by the Valsalva maneuver (VM). Seventy-nine TGA patients with complete ultrasound examination data during admission were recruited prospectively to evaluate IJV drainage, which included the time-averaged mean velocity, and the cross-sectional lumen area of the IJV at the vein's middle (J2) and distal (J3) segments and the cross-sectional area during a 10-s VM to test for any retrograde or anti-grade flow. Forty-five TGA patients and 45 age- and sex-matched control subjects underwent complete contrast-enhanced magnetic resonance (MR) venous studies, which included time-resolved imaging of contrast kinetics, contrast-enhanced axial T1-weighted MR imaging, and phase-contrast-based non-contrast enhanced magnetic resonance venography (MRV).

Hippocampus 2019 Jan 31. Epub 2019 Jan 31.

Memory Disorders and Plasticity Group, Department of Neurology, University Hospital Schleswig-Holstein, Kiel, University of Kiel, Kiel, Germany.

Day-to-day life involves the perception of events that resemble one another. For the sufficient encoding and retrieval of similar information, the hippocampus provides two essential computational processes. Pattern separation refers to the differentiation of overlapping memory representations, whereas pattern completion reactivates memories based on noisy or degraded input. Read More

[Cognitive deficits associated with electroconvulsive therapy for depression: moderating factors and neuropsychological tests].

Fortschr Neurol Psychiatr 2018 11 17;86(11):690-698. Epub 2019 Jan 17.

Klinik und Poliklinik für Psychiatrie und Psychotherapie Heinrich-Heine-Universität, Medizinische Fakultät, Düsseldorf.

Due to the efficacy of electroconvulsive therapy (ECT) in the guideline-based treatment of therapy-resistant depressive episodes and the clinical significance of cognitive impairments, it is necessary to optimize the management of potential side effects. As cognitive side effects of the treatment combined with impairments resulting from the depression may lead to a reduction in the ability to function in social contexts and reduce subjective wellbeing, comprehensive information about and monitoring of potential side effects is essential. In this review we present the clinical relevance and measurement of cognitive side effects that may occur during electroconvulsive therapy. Read More

Impaired Consciousness in the Emergency Department.

Eur Neurol 2018 12;80(3-4):179-186. Epub 2018 Dec 12.

Department of Neurology, Hospital of the Ludwig-Maximilians-University (LMU), Munich, Germany,

Background: The approach to unconscious patients in the emergency department (ED) is difficult, often depends on local resources and interests, and workup strategies often lack standardization. One reason for this is that data on causes, management, and outcome of patients who present to the ED with sudden onset unconsciousness of unknown cause is limited.

Objectives: This study was performed to analyze the causes of acute impaired consciousness in patients in an interdisciplinary ED. Read More

Department of Neurology, UniversitätsMedizin Mannheim, Heidelberg University, Mannheim, Germany. Electronic address:

Introduction: Stress-related transient inhibition of memory formation in the hippocampus has been hypothesized as one of the underlying pathomechanisms of transient global amnesia (TGA). TGA episodes, during which patients cannot encode and recall new information (anterograde amnesia affecting episodic long-term memory), are frequently preceded by a psychologically or physically stressful event.

Methods: We measured salivary cortisol during acute TGA in 14 patients, as well as cortisol day-profiles and the effect of experimental exposure to stress (using the socially evaluated cold pressor test) on cortisol levels during the subacute phase. Read More

[Tips for taking the medical history in patients with syncope].

Authors:
Carsten W Israel

Herzschrittmacherther Elektrophysiol 2018 Jun;29(2):144-154

Klinik für Innere Medizin - Kardiologie, Diabetologie & Nephrologie, Evangelisches Klinikum Bethel, Burgsteig 13, 33617, Bielefeld, Deutschland.

Transient loss of consciousness represents one of the most frequent reasons for patients to present in the emergency room. Already at the very beginning, the diagnostic work-up is faced with fundamental questions: (1) Was it really a loss of consciousness? (2) Which department (neurology, cardiology, or others) should check the patient? (3) Is an in-hospital diagnostic work-up required? These questions can be answered from a meticulous patient history which needs to be adjusted to the individual case but also has to systematically go through a list of questions. Patient history has to clarify whether syncope was present. Read More

2 Sleep Disorders Unit, Institute of Neurology, Catholic University, Rome, Italy.

Transient global amnesia (TGA) is a clinical syndrome characterized by retrograde and anterograde amnesia without other neurological deficits. Although electroencephalography (EEG) methods are commonly used in both clinical and research setting with TGA patients, few studies have investigated neurophysiological pattern in TGA using quantitative EEG (qEEG). The main aim of the present study was to extend these previous findings by exploring EEG power spectra differences between patients with acute TGA and healthy controls using the exact low-resolution brain electromagnetic tomography software (eLORETA).

Relationship between Cytotoxicity in the Hippocampus and an Abnormal High Intensity Area on the Diffusion-weighted Images of Three Patients with Transient Global Amnesia.

Intern Med 2018 Sep 27;57(18):2631-2639. Epub 2018 Apr 27.

Division of General Medicine, Department of Medicine, Nihon University School of Medicine, Japan.

Objective An abnormal high intensity area (HIA) on diffusion-weighted imaging (DWI) indicates the presence of cytotoxic edema and has been reported to be observed in the hippocampus of patients with transient global amnesia (TGA). The appearance of an HIA on DWI is usually delayed after the onset of patients with amnesia in TGA; thus, the significance of the HIA was evaluated in patients with TGA. Methods Three adult TGA patients who had a unilateral HIA on DWI (right, n=2; left, n=1) were enrolled. Read More

Transient neurologic syndromes: A diagnostic approach.

Cleve Clin J Med 2018 Feb;85(2):155-163

Mellen Center for Multiple Sclerosis, Department of Neurology, Cleveland Clinic, Cleveland, OH, USA.

Clinicians are often confronted with patients who have transient neurologic symptoms lasting seconds to hours. In many of these patients, their symptoms have gone away or returned to baseline by the time of evaluation, making the diagnosis even more challenging. Elements such as correlation of symptoms with vascular territory, prodromes, triggers, motor symptoms, confusion, and sleep behavior can guide the diagnostic workup. Read More

3 Neurologie, Kantonsspital Graubünden.

Transient global amnesia (TGA) is a neurological condition which is still a diagnostic challenge for clinicians. Diagnostic clues are an acute onset of a disturbance of memory, a lack of other focal neurological deficits, and repetitive questioning of the patients about time and circumstances. Although the signs and symptoms are quite typical, making the diagnosis of TGA might still be challenging, depending on the patient’s characteristics. Read More

Transient global amnesia: current perspectives.

Neuropsychiatr Dis Treat 2017 24;13:2691-2703. Epub 2017 Oct 24.

Department of Psychiatry and Behavioral Sciences, Eastern Virginia Medical School, Norfolk, VA, USA.

Transient global amnesia (TGA) is a clinical syndrome characterized by the sudden onset of an extraordinarily large reduction of anterograde and a somewhat milder reduction of retrograde episodic long-term memory. Additionally, executive functions are described as diminished. Although it is suggested that various factors, such as migraine, focal ischemia, venous flow abnormalities, and epileptic phenomena, are involved in the pathophysiology and differential diagnosis of TGA, the factors triggering the emergence of these lesions are still elusive.

Perturbation of corticohippocampal circuits is a key step in the pathogenesis of transient global amnesia. We evaluated the spatial distribution of altered cerebral metabolism to determine the location of the corticohippocampal circuits perturbed during the acute stage of transient global amnesia. A consecutive series of 12 patients with transient global amnesia who underwent F-fluorodeoxyglucose positron emission tomography within 3 days after symptom onset was identified. Read More

Transient global amnesia following a whole-body cryotherapy session.

BMJ Case Rep 2017 Oct 13;2017. Epub 2017 Oct 13.

Spitalzentrum Biel AG, Biel, Switzerland.

Whole-body cryotherapy (WBC), which consists of a short exposure to very cold and dry air in special 'cryo-chambers', is believed to reduce inflammation and musculoskeletal pain as well as improve athletes' recovery. This is the case of a 63-year-old male, who presented with transient global amnesia (TGA) after undertaking a WBC session. TGA is a clinical syndrome characterised by a sudden onset of anterograde amnesia, sometimes coupled with a retrograde component, lasting up to 24 hours without other neurological deficits.
